The next day, everyone started their own investigations, and Nangong Yi went to compare the murders with similar techniques in the crime files according to the characteristics of the murderers we analyzed, trying to accurately identify the murderers.

Yun Duruo, Han Yu and the crown prince returned to Hede Medical College to start investigating the rumors about the underworld, and I would like to do a detailed autopsy on Sun Xin to see if there are any new discoveries.

Because Sun Xin's case does not belong to the category we took over after all, Sun Xin's body was sent to the police station, and when I went, I happened to meet Song Chi, and I knew that he had stayed up for a long time in a row, and the whole person was tired and haggard.

"Has there been any progress in the investigation?" I asked by patting him on the shoulder.

"It's tricky, and this murderer is too cunning to leave any clues." Song Chi said as he handed over a cigarette, and as soon as I wanted to light it, I saw Song Chi suddenly straighten up.

His expression looked like he was facing a great enemy, and I didn't have to look back to know who was standing behind me, so I quickly turned around and habitually straightened up.

Report ......

Suddenly, he found that there was still a cigarette in the corner of his mouth, and he took it off and looked at the butcher opposite him with a serious expression.

It seems that this is the first time I have seen him since he was expelled, and he still has a smiling face, looks at me with his hands behind his back, and nods silently.

"Your Aunt Tan has been talking about you and Du Ruo, and I have time to see her."

The butcher was still so familiar, but he suddenly found that he was much older, although he was still expressionless, but his voice seemed to be much softer, and after speaking, he walked over, looking at his twilight back, and suddenly there was an inexplicable sadness in his heart.

"The butcher is hard-mouthed, obviously he misses you and Du Ruo, if you have to say that Aunt Tan wants it, then you take the time to really take a look, after you and Du Ruo left, the butcher's temper became bigger and bigger, and he shouted at the door several times."

"Shouting what?"

"You don't know his temper, who bites whom, when he encounters a tricky case, he often throws a report and smashes things, tears his throat and shouts at the door, call Rong Yan and Yun Duruo to me......" Song Chi lit a cigarette and said with a gloomy expression.

I sighed silently in my heart, I was used to the days of forty innings, but I didn't expect that it was the butcher who yelled at us every day before that I couldn't let go, Song Chi said that every time the butcher shouted something, he sat on the chair in a daze without saying a word.

"Go back and Yun Duruo and I will go to see him, I have forgotten about this matter a lot recently, the butcher seems to be really old, and he has begun to learn to talk to people." I took a puff of my cigarette and said to myself.

"By the way, what are you doing here?" Song Chi asked.

"I want to check Sun Xin's body again." I say.

"When you come back here, you should go home, I won't go if you go by yourself, there are still many things." Song Chi nodded and smiled casually. "I just found the last person to see Sun Xin, and he was actually from Hede Medical College, thinking that there was a breakthrough, but there was still no progress."

"Hede Medical College?" I grabbed Song Chi and asked in surprise. "What is the name of the person who last saw Sun Xin?"

"Call ......," Song Chi opened the file in his hand and looked at it and answered. It's called Hua Guanwen. ”

I was stunned for a moment and repeated Hua Guanwen's name, Song Chi saw that my expression was so solemn and shocked, and asked me what was wrong, I licked the corners of my mouth and remembered our previous analysis of the murderer.

The murderer is a male, roughly between 35 and 60 years old, the murderer has very good medical knowledge, and the murderer has a strong obsessive-compulsive disorder......

These characteristics are completely consistent with Hua Guanwen, except for the last one, the murderer is very likely to suffer from a serious mental illness, and I suddenly remembered that every time I saw Hua Guanwen, he was eating all kinds of food......

I didn't dare to think about it anymore, Song Chi saw that I didn't speak for a long time with a solemn face, and urged him eagerly, so I told him about the results of our analysis of the murderer and Hua Guanwen's situation.

"Do you suspect that Hua Guanwen is the murderer?" Song Chi asked.

"Didn't you just say that he was the last person to contact Sun Xin, he completely fits the characteristics of all murderers, of course, there is still a need to verify the aspect of cannibalism." I replied.

"Absolutely impossible, I also thought before, the last person who contacted Sun Xin was likely to be the murderer, but it was later confirmed that although Hua Guanwen was indeed the last person to see Sun Xin, he must not be the murderer." Song Chi said categorically.

"Why?" I asked, confused.

Song Chi pulled me to the bench next to me and sat down, and said to me while smoking a cigarette that the floor where Sun Xin stayed belonged to the highest specification suite, and the card had to be swiped to otherwise it would not be possible to reach it, and the police retrieved all the people who went in and out of Sun Xin's floor on the night of the crime, and found that the last person to see Sun Xin was a man named Hua Guanwen.

According to the hotel service staff's recollection of that night, Hua Guanwen talked to Sun Xin on the phone at the front desk, telling Jiang Xinyu that he could not go to the appointment on time because of an emergency, and he came to visit Sun Xin as the vice president of Hede Medical College, because Sun Xin came back The most important itinerary is to meet Jiang Xinyu, and the two will have a just opened academic exchange symposium, Hua Guanwen came to discuss some of the details on behalf of Jiang Xinyu and Sun Xin.

And Sun Xin agreed to go upstairs after learning Hua Guanwen's identity, at about 11 o'clock in the evening, Hua Guanwen left the hotel when the front desk waiter saw him, and no one else went to see Sun Xin.

"That's just right, I've seen the autopsy results, Sun Xin's death time was between ten and twelve o'clock in the evening, Hua Guanwen left just in this time period, he is very suspicious, why are you so sure that the murderer is not him?" I asked seriously.

Because not long after Hua Guanwen left, Sun Xin went to the front desk to ask for a replacement because the key card could not be used!

I was stunned for a moment and finally understood why Song Chi was so sure that Hua Guanwen was not the murderer, Sun Xin did not die when he left, and it was eleven o'clock in the evening, since the people at the front desk saw Sun Xin, it explained that the exact time of Sun Xin's death was between eleven and twelve o'clock.

Song Chi said that Sun Xin did not return to the room after dealing with the key card, but went out of the hotel to do something, and they did not know when Sun Xin returned to the room, but it was very certain that no one had ever seen Sun Xin again on the night of the crime.

According to what Song Chi learned, Sun Xin should have been killed after returning to the room, my suspicion of Hua Guanwen is obviously wrong, but how did the murderer enter the room and leave?

"I'm thankful for that easy, hey...... Looks like I don't want to go home tonight. Song Chi stood up, snuffed out the cigarette butt, and said to me with a wry smile. Autopsy, you are an expert, help my brother to see if there is anything missing, otherwise the case will not be solved, I don't know how the butcher will scold me. ”

I smiled helplessly and nodded, after separating from Song Chi, I walked back to the dissection room, and when I changed my clothes, I suddenly had a feeling of being in a different world, everything here is so familiar, all the bits and pieces that happened here are as if they were yesterday, and now I remember it vividly.

"Rong Yan?" The voice behind him was a little hesitant, but he couldn't hear it too sure.

I turned around and saw that it was Lao Yang from the bureau, to be exact, he was not a person from the bureau, he was responsible for guarding the morgue, because the body found at the murder scene would be handed over to the forensic department for autopsy, and before the complete autopsy report came out, the body was stored in the morgue of the police station, and it could only be handed over to the family of the deceased after all the necessary processes were completed.

And Lao Yang is responsible for managing the morgue and handing over the body to the deceased's family, he has been in the bureau for a lot longer than me, because of his previous work, he often deals with him, he is much older than me and is a senior, I have always respected him, Lao Yang has a good impression of me, he also didn't understand this when I was expelled, and let me come back often on the day I left.

When I turned around and saw that it was really me, Lao Yang laughed overjoyed, chatted with him for a few words, and explained the intention of this time, Lao Yang acted very quickly and asked me to go to the autopsy room first and wait, and he immediately sent the body to me.

After Lao Yang sent Sun Xin's body, he was afraid of disturbing my work, so he closed the door and went out, I put on gloves and began to seriously examine Sun Xin's body, the previous autopsy report I have read many times, Sun Xin did not find any external injuries on his body, only found a bound bruise on his wrist.

I flipped through Ling Guodong's on-site investigation report and found one of the photos of Sun Xin at the scene, which was taken from behind Sun Xin's body, Sun Xin was sitting on a chair with her hands down and each tied to either side of the chair.

Another photo is a close-up of Sun Xin's hands tied, Sun Xin's palms are outward, bound by thin ropes, but the way of binding is very special, and the knot is rare at the end, a bit like the form of a wishful knot, the way the left and right hands are tied and knotted is the same, it can be seen that the murderer was not very flustered and casual when tying Sun Xin, and this knot must have a special meaning for the murderer.

I frowned and felt a little unreasonable, Sun Xin had been injected with anesthetic by the murderer and had had the prefrontal lobe removed when she was tied up, Sun Xin could not have the ability to resist, and she didn't even have emotional awareness, as for the complete loss of mobility, such a Sun Xin murderer didn't have to worry about her resisting and struggling at all, so why did she have to tie up Sun Xin?

When examining the wound on Sun Xin's head, I found that the connection between Sun Xin's brain stem and spine was severed, which was the cause of Sun Xin's fatal death.

The undigested food found in the stomach of the deceased was actually Sun Xin's own brain, which also verified our previous inference that when the murderer ate her brain, he did not forget to let Sun Xin eat it himself, which shows that the murderer is extremely perverted to the point of outrageousness.

After three hours of autopsy, I was tired and weak, which was basically consistent with the autopsy report, but I didn't find anything unusual from the corpse.
